Running. Hiding. Surviving.

Anchorage, once Alaska’s largest city, has fallen. Now a threatening maze of death, the city is firmly in the cold grip of a growing zombie horde.

With life and death hanging on every decision, Neil must face each new obstacle without breaking. And the group presses on toward their last hope: that this nightmare has been contained, and there still exists a sane world free of infection.

But to reach it, they must survive and escape...
